The first parameter of prepare_lock_switch (kernel/sched/sched.h) is not
used anymore. Commit c55f5158f removed the code that use the first
parameter and function prepare_lock_switch is only used in
prepare_task_switch (kernel/sched/core.c)
I tested it in a virtual machine running Debian x86_64 with kvm. I
also tested it in my computer which is a x86_64 machine running Arch Linux
and everything is fine.
